Frequently asked questions
About the TLC9803
What is the difference between a Holter and a resting ECG?
A resting ECG records a few minutes in the clinic. A Holter records 24 hours while the patient moves normally, catching what happens at different times of day.
Who reads the recording?
The cardiologist. The software analyses and displays; the diagnosis is the physician's decision.
Are leads and spares available?
Yes, genuine Holter leads and transfer cables are available from us.
What does it run on?
2 × AA batteries; recordings transfer to the computer over USB 2.0.
Can the patient mark a symptom?
Yes, there is an event-mark key on the recorder, and the physician finds the mark in the recording.
